' ATTACHMENT FonhconLEnA'ron PEDALS.

Application filed April 28, 1924. SeriaiN'o. 709,550.

To allwhom'z't may concern: 1

. Be it known that I, Jeanne M. BRENNAN, a citizen of the United States, and a resi dent of Los Angeles, in the countyof Los Angeles and State of California, have invented certain new and useful Improvements in Attachments for Accelerator Pedals, of which the following is a specification.

'My invention relates to and has for its purpose the provision of an attachment for accelerator pedals adapted'to control or stabilize' internal combustion engmes, by means steadied sufficiently to prevent the sudden, jerky ing of the throttle when the car is traversing rough roads; v

It is also a purpose of my invention to.

provide an accelerator pedal attachment of the above. described character embodying a body wholly supported on the pedal and sufliciently rigid to allow the gradual application of, foot pressure in depressingthe pedal, but which, when subjected to sudden pressure, collapses or yields to preventthe transmission of such pressure to the pedal.

I will describe only one form of attach.- mentfor acceleratorpedals embodying my invention, and will then point out the novel features thereof in claims.

In the accompanying drawings Figure 1 is a view showing in side elevation a standard form of accelerator pedal having applied thereto one form of attachment embodying my invention;

Figure 2 is an enlarged sectional view of the attachment in applied position on the pedal;

Figure 3 is a top plan view of the attachment; and

Figure 4 is a bottom plan view.

Referring specifically to the drawings, in

which similar reference characters refer to similar parts, my invention in its present embodiment comprises a supporting plate 15 which, in the present instance, is a metal disk provided with a peripheral annular flange l6. Soldered or otherwise secured to the under side of the disk 15 are intersecting strips 17 of such length as to provide fingers which are bendable to engage the head 18 of an accelerator pedal 19 and to thus securely hold the disk in firm position upon the head.

Supported on the plate 15 is a hollow resilient body 20, such body in the present and unintentional opening and clos instance being formed of. rubber and of semi-spherical formation." The body as a unit is confined upon the plate by means of a flange 16 engaging the edge of the body, as clearly shown in Figure 2, and this body is formed. with, a bleeding port 21 to" allow the passage of air inwardly or outwardly of i the body. V V i y In practice, the attachment is applied to the head 18 of the pedal 19 by bending the finger 1'? in the manner shown, whereby the,

body 20 is securely held-in superimposed position with respect to theiipedal head 18 for engagement bythe foot ofithe operator. The body 20 is designed to withstand, without appreciably yielding or collapsing, foot pressure applied to the apex thereof, thereby providing a rigid connection between the foot and pedal sovthat; the pressure-of thefoot Wlll operate to; depress the pedal. :It will be understood that foot pressure. 1ap-' plied to theapex of the body will tend, owing to the curved formjof the body, to compressthe side walls thereof and thus/set up the necessary rigidity to prevent collapsing. v The air confined within the body also aids in preventing the collapsing of the body owing to the restricted 01113181121.

However, should foot pressure be suddenly applied to the body, that is, pressure at a rate appreciably: exceeding the downward movement of the pedal, the body will yield to such sudden pressure and thereby prevent its transmission to the pedal 18. It will thus be seen that this depressing movement will be ineffective to depress the pedal.

' From the foregoing operation it will be manifest that in practice the body 20 pro- Vides a rigid connection between the foot and pedal to allow the gradual depression other heat insulating material, the transmission of heat from the accelerator pedal to the foot of the operator is prevented, thereby eliminating the burning sensation experienced in making trips of long duration. Further, the fact that the member 20 is formed of relatively soft material, a

cushion is provided between the accelerator pedal and the foot which prevents the formation of callous spots upon the footnof the. operator. f

Although I have herein shown and described only one form of accelerator pedal attachment embodying my invention, it is to be understood that variouschanges and:

modifications may be made herein without departing from. the spirit of the invention and the spirit. and scope of: the appended claims. 7 I
